It's a lot about the base. The 1-2 combination of a supportive mattress and well-built foundation is just what you need for restful sleep. With solid wood construction, a diagonal bar and corner supports, there's extra support and durability built into this split queen foundation. The smooth nonskid surface holds every style of mattress in place, including hybrid, memory foam and innerspring mattresses. Please note: a split queen mattress requires two foundations (sold separately).
